[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-7 A novel prefabricated cabin includes two prefabricated cabin bodies 1, each made of corrugated board. A movable door 2 is installed at the outer end of each prefabricated cabin body 1. Two ventilation components 5 for heat dissipation are provided on the outer side of each prefabricated cabin body 1. Multiple corner pieces 3 are fixedly installed at several corners on the outer end of each prefabricated cabin body 1. Connecting components 4 are provided at the outer ends of each corner piece 3. The two prefabricated cabin bodies 1 are detachably connected together via multiple connecting components 4. Each connecting component 4 includes a movable frame 45, a second hook 48, and a first hook 43. The movable frame 45 is limited by being engaged with the second hook 48 and the first hook 43.

[0037] A base 6 is fixedly installed at the bottom of the prefabricated cabin 1, and two slots 7 are opened on the outside of the base 6.

[0038] The equipment in this solution is mainly used for installing various electrical devices. By prefabricating them in the factory and transporting them directly to the installation site, there is no need to wait for customization, which improves construction efficiency. Furthermore, mass production reduces production costs. The prefabricated cabin 1 in this solution is similar to a shipping container, made of galvanized corrugated steel sheet, giving it high strength and low cost. It is worth mentioning that the prefabricated cabin 1 in this solution can also be modified from shipping containers, further reducing production costs. A movable door 2 is installed on the front of the prefabricated cabin 1. The movable door 2 can use the same type of door as a shipping container door. There are eight doors on the prefabricated cabin 1. Each corner is fixed with a corner 3, and each corner 3 is equipped with a connecting component 4. The prefabricated cabin 1 can be used alone, or multiple prefabricated cabins 1 can be connected by connecting multiple connecting components 4. After the ends of multiple prefabricated cabins 1 are brought together, the U-shaped hooks 47 on the connecting components 4 are hooked into the hook grooves 411, and the movable frame 45 is rotated backward so that the second hook 48 is locked in the first hook 43. This allows two prefabricated cabins 1 to be connected together, increasing their internal volume. This can meet the size requirements of different projects and improve construction efficiency. At the same time, the multiple detachable prefabricated cabins 1 can be transported separately, improving the convenience of transportation.

[0039] Ventilation components 5 are installed on both sides of the prefabricated cabin 1. By setting the first partition 52 and the second partition 53 at an angle and parallel, external rainwater can be prevented from entering. The inner baffle 2 55 and the inner baffle 1 54 installed on the first partition 52 and the second partition 53 respectively are used to prevent insects from flying in. Thus, the ventilation components 5 can not only ensure the airflow and heat dissipation inside the prefabricated cabin 1, but also prevent insects and other debris from entering and interfering with electrical equipment, thereby reducing the failure rate.

[0040] A base 6 is fixed at the bottom of the prefabricated cabin 1. Two slots 7 are opened at the outer end of the base 6. The slots 7 run through the entire base 6. When loading and unloading the prefabricated cabin 1, a forklift can be used to insert into the slots 7 for loading and unloading, which improves the convenience of loading and unloading.

[0041] Please see Figures 3-5 The connecting component 4 also includes a first fixed seat 41 and a second fixed seat 42. The first fixed seat 41 and the second fixed seat 42 are respectively fixedly installed on the outer ends of the box corners 3 on the two prefabricated cabins 1. The movable frame 45 is rotatably installed on the outer end of the first fixed seat 41. A handle 44 is fixedly connected to the end of the movable frame 45 away from the first fixed seat 41.

[0042] The connecting assembly 4 also includes a mounting shaft 410 and a U-shaped hook 47. The mounting shaft 410 is rotatably mounted on the outer end of the movable frame 45, and the mounting shaft 410 extends to the outside through both ends of the movable frame 45. The two ends of the U-shaped hook 47 are fixedly connected to the two ends of the mounting shaft 410 respectively. The outer end of the fixed seat 42 is provided with a hook groove 411, and the U-shaped hook 47 matches the hook groove 411.

[0043] A pressing block 46 is fixedly installed on the outer end of the second hook 48. The second hook 48 is rotatably connected to the inner side of the movable frame 45. Two spring pieces 49 are fixedly installed on the bottom end of the pressing block 46. The side of the spring piece 49 away from the pressing block 46 abuts against the outer end of the movable frame 45. The pressing block 46 drives the second hook 48 to rotate upward through the force of the spring piece 49.

[0044] The connecting component 4 in this solution is mainly used to connect multiple prefabricated cabins 1 together. During use, fixing seat 1 41 and fixing seat 2 42 need to be fixed to the outside of the corner 3 of the two prefabricated cabins 1 to be connected. Fixing seat 1 41 and fixing seat 2 42 can be fixed with bolts. The movable frame 45 is in a clamping state, allowing the top of fixing seat 1 41 to be rotatably connected to the inside of the movable frame 45. A handle 44 is also fixed to the outer end of the movable frame 45, mainly for easy gripping. The mounting shaft 410 passes through the movable frame 45. It can also rotate within the movable frame 45. The two ends of the U-shaped hook 47 are respectively fixed to the two ends of the mounting shaft 410 extending outward, so that the U-shaped hook 47 can drive the mounting shaft 410 to rotate. A hook groove 411 is opened on the fixed seat 2 42. When the U-shaped hook 47 is hooked into the hook groove 411, the movable frame 45 is rotated downward, so that the U-shaped hook 47 can move towards the fixed seat 1 41, so that the U-shaped hook 47 can tightly connect the fixed seat 2 42 and the fixed seat 1 41 together, so that the two prefabricated cabins 1 can be connected together.

[0045] Inside the movable frame 45, a second hook 48 is rotatably connected, while a first hook 43 matching the second hook 48 is fixed on the fixed base 41. When the second hook 48 and the first hook 43 are engaged, the connection is complete. A pressing block 46 is fixed to the top of the second hook 48, and two spring pieces 49 are fixed to the bottom of the pressing block 46. The spring pieces 49 are V-shaped and made of metal, with a certain degree of elasticity. They can push the pressing block 46 upward through their own elastic force, so that the second hook 48 always tends to move forward and hook the first hook 43. When the second hook 48 and the first hook 43 are engaged, the force of the spring pieces 49 makes it difficult for the second hook 48 and the first hook 43 to disengage. When it is necessary to release, simply press down on the front end of the pressing block 46 to move the second hook 48 backward, and the engagement can be released. At this time, the movable frame 45 can be rotated, and the force of the spring pieces 49 can improve the stability of the connection.

[0046] It is worth mentioning that when multiple prefabricated cabins 1 are connected end to end, only the tail plate of the prefabricated cabin 1 needs to be removed. At this time, the movable door 2 in the middle can also serve as an internal isolation door. Structural adhesive needs to be applied to the gaps at the connection of each prefabricated cabin 1, both on the outside and inside, so that the connection will not leak.

[0047] Please see Figure 6 and Figure 7 The ventilation component 5 includes a fixed frame 51. A ventilation opening is provided on the outside of the prefabricated cabin 1. The fixed frame 51 is fixedly installed on the inside of the ventilation opening. Multiple partitions 1 52 and multiple partitions 2 53 are fixedly installed on the fixed frame 51.

[0048] Partition 1 52 and partition 2 53 are arranged in parallel, and a ventilation gap is provided between partition 1 52 and partition 2 53. An inner baffle 1 54 is fixedly installed at the outer end of partition 1 52, and an inner baffle 2 55 is fixedly connected to the outer end of partition 2 53. Both inner baffle 1 54 and inner baffle 2 55 are located within the ventilation gap.

[0049] In this design, the prefabricated cabin 1 has ventilation openings on both sides. A fixing frame 51 is fixed inside each ventilation opening. Each partition 1 52 and partition 2 53 can form a set. Multiple sets are installed inside the fixing frame 51. Partitions 1 52 and 2 53 are inclined and parallel, similar to traditional louvers. The gap between partitions 1 52 and 2 53 is a ventilation gap, allowing air circulation between the inside and outside of the prefabricated cabin 1. The inclined partitions 1 52 and 2 53 also prevent rainwater from entering. Inside the prefabricated cabin 1, inner baffles 1 and 2 are fixed to the partitions 52 and 53 respectively. The inner baffles 1 and 2 are arranged in parallel and located in the ventilation gap between the partitions 52 and 53. They block the air inside the ventilation gap in a curved channel. When insects or debris from the outside enter the ventilation gap, they are blocked by the inner baffles 1 and 2, which reduces the probability of them passing through. This reduces the impact of insects or debris on the electrical equipment inside the prefabricated cabin 1 and lowers its failure rate.

[0050] Working principle: When two prefabricated cabins 1 need to be connected together, firstly, fix the first fixed seat 41 and the second fixed seat 42 to the outside of the corner 3 of the two prefabricated cabins 1 that need to be connected. Then, hook the U-shaped hook 47 into the hook groove 411 and rotate the movable frame 45 downwards. This will allow the U-shaped hook 47 to move towards the first fixed seat 41, so that the U-shaped hook 47 can tightly connect the second fixed seat 42 and the first fixed seat 41 together. At the same time, due to the driving force of the movable frame 45, the second hook 48 and the first hook 43 will also fit together, so that the two corner 3 can be connected together. At the same time, through the force of the spring piece 49, the second hook 48 and the first hook 43 will not easily detach. Then, install the four connecting components 4 in sequence to connect the two prefabricated cabins 1 together.
